i a, whore it] may concern:

Be it known that we, MARIE A; BLooM- FIELD, of the borough of Manhattan, and HER- BERT E; HAWES, of; the borough of Brooklyn,

iuthe city and Stateof New York, citizens of the United States, have jointly invented certain new and useful Improvements in Marking Attachments for Sewing- Machines, of

which the following isa specification, refertokence being hadtoj the'accompanying drawings, in whichr v Figural is a side view of our. invention, certain'of the parts being illustrated in dotted lines because of their position behind'other t5, pa l-ts from the point of view of the observer.

Fig. 2'is a top view of certain parts of our said invention, and Figs. 3, 4,-and 5 are views of details. Y

Thebbject of our invention is to producea marking mechanism or attachment to the or-' dinary sewing-machine which shall be simple land effective in its construction andwill enable the operator on the machine to automatically mark on thefgoods continuouslines in desired places which shall serve as guides for subsequent treatmentor sewingof thegoodsas, for instanee,in sewing so-called tucks to -inark continuously the goodsand parallel'with the lineof the seam while the same are being 3o sewed so as to designate on the goods the location of", the next fold required to be'made in order to sew the next tuck; and it is also the object of our inventionv to efiect such marka ing as aforesaid without the exertion of other 3 5 power or attention on the part of the operator than heretofore during the progress of the ,sewing. V a. t. a In the drawings, A represents the presserbar of the ordinary and well-known type of 4o'sewing-machine, to which we secure bysetscrew a, operatiugin'a yoke or s1eeve:b, -the supporting-sleeveB. In thesupporting-sleeve 13 turns the shaft 0, having fixed th'ereto on' one side of said slee-vethe ratchet wheel D 'and on the other side the gear-wheel E, ad-

joining a'nd'outside of which and sleeved upon the shaft 0 is the actuating-link F, within,

which turns the shaft a, carrying fixed thereto at its inner end the gear-wheel d, meshing 5o with the gear-wheel and also turning in said the continuation of said last-mentioned shaft passing between the needle Nandthe s'aid ipre'sser bar A, and preferably graduatedand carrying the sleeved marker-wheel and its supporting parts, as hereinafter described.

To the needle-bar H of the machine one end of the connecting-link I is pivotally secured in any convenient manner, as by the adjustable and removable clamp h, through which is threaded the set-screw h, which bears upon the needle-bar H, and thus causes theelamp h to engage and draw against the bindingplate k (See Fig. 3.) The other end of said .link I-,is pivotally connected, as at J, with." another link I, which latter at its opposite extremity is 'ournaled upon the said shaft 0 and provide-Li with a pawl P, engaging in the teeth of the ratchet-wheel D.

W is v a circular marker-wheel, preferably constructed of chalk or other material sufii-V *cientlys'oft to be abraded by friction against,

the goods. The said wheel is mounted upon the exteriorly-threaded sleeve K, having the flange or headl'a and upon which rides the flange k. The marker-wheel disk is centrally bored-out, so as to'a'dmit of its being passed over the threa'dedsleeve K and so as: So to bear against the flange 1c. .The follower for washerf flange k is likewise bored out and .placed inposition, asshown, next to and on theoutside ofxthe marker wlieel. A milled nut L, internally threadedto correspond with thelscrew of K, is then screwed down'uponthe latter,ithus firmly clamping the markerwheel in position, which, with its thus con-' nected parts; will now slide up and down the shaft e to the desired location,'as indicated 0 by the graduated scale thereon, and there it may be firmly fixed by turning the set-screwM. :0 is a springone extremity-of-whiclfis fixed to and bears upon the supporting-sleeve B and the other upon the actuating-link F, so as to depress the latter, with the markerwheel, and thus insure su'ffieiently forcible hearing by the latter against the goods. The operation of my invention is as follows: The presser-bar A is inserted in the zoo sleeve and the latter firmly fixed-upon the former by screwing down the set-screw aiat such a point as to insure'a moderate pressure upon the goods' by" the marker-wheel W. The movable clamp h and binding-plate h are next placed in position at snch'a ,point.

on the needle-bar H as to in'su re proper action by the pawl P, as hereinafter described. The

spring is next adjusted soas to operate with such sufficient force upon the markerwheel as to insure-its constant pressure upon the goods, and thus compensate for its diminishing diameter due to wear against the goods. The goods being sewed are fed in the direction of the arrow P- .The reciprocating movement of the needle-bar H communicates such motion to the pawl P as to cause it to operate upon the ratchet-wheel D, and thus rotate the shaft 0 with its gear-wheel E, the latter meshing with the gear-wheeld, which in turn causes the gear-wheel G and its shaft e, carrying the marker W, to rotate in-a direction opposite to that in which the goods are being fed,-and thus the marker is caused to inter-- 'mittently brush positivel/y against the goods,

and thus mark them plainly while they are held by the needles passing through them.

By'means of the set screw M, gage'e,and

other parts entering itrto the mounting of the marker-wheel W, as gheretoforestated, the

y latter may be moved readily and set at substantially any requireddistance from the scam which is being sewed; By this means and without in any way interfering with the usual operation of the machine and its parts the goods may be simultaneously with the sewing automatically marked parallel with vice, as aforesaid, affording in such a case a.

and at any usually required distance from the seam, and thus the labor of separately preparing and markrn g the goods for the nexttuck in tucking, for instance, is greatly diminished, the mark-line produced by our deguide or location'ofthe line along-which the material is to be folded in making the next tuck. In certain kinds of sewing it may be more desirable to rotate the marker in the same direction as thefeed of the goods, and this may be readily accomplished by inserting another geared-wheel in the train carried by the actuating-link F.

What we claim as new, and desire to secure by Letters Patent, is

1. In combination with a sewing-machine:

" mechanism-a marker-wheel of abradable material and means for intermittently rotating the same while the needle is in the goods.

2. In combinationwith a sewing-machine mechanism an abradable rotatory markerwheel: intermittently rotating; while the needle is in the 4 goods and mechanism. connee-ting the'reciprocating' needle-bar with the said'wheel for the purpose of rotating-the latter.-

3. The combination of a sewing-machine with an abradable rotatory marker-wheel rotating intermittently while theneedle is in the goods and carried atone extremity of a link F the opposite extremity of which is carried on a yoke I) supported von the presser-bar A and mechanism connecting the marker-wheel with the reciprocating needle-bar to cause said marker+wheel to rotate as aforesaid.

4. In combination with a sewing-machine mechanism, a rotatory marker-Wheel rotating intermittently while the need-1e is in the goods, the link F, shaft e, andgear-wheels G,

D; E, shafts G, C, ratchet-wheel D, connecting-links I and 1', spring 0, spring-pawl P, yoke-or sleeve 13, set-screw A.

5. In combination with a sewingmachine mechanism, a rotatory marker-wheel rotating intermittently while. the needle is in thev goods, the link F, shaft e, and gear-wheels G,

D, E, shaftsc', C, ratchet-wheel D, connecting-links I and I, spring 0 spring-pawl P,

yoke or sleeve B, set-screw'A, removable clamp h, and set-screw h.

6. In combination with a sewing-machine mechanism, a rotatory marker-wheel rotatnecting said needle-bar with said shaft.

8. In combination with a sewing-machine mechanism a positively-rotated marker-wheel of abradable material and means to actuate and connect the same operatively with the I needle-bar.

9. In combination with a sewing-machine mechanism a positively-rotated marker-wheel of abradable material yieldingly held against the goods, and means for actuating the same.
